"Could you at least take the sunglasses off?"
At that point, she straight up mounts Mr. Thorton, who has the choice between saying "No Way In Hell" or the less-than-enthusiastic, "Might As Well." So there's a "consent" option, but even that is dubious, considering her response is, "I thought I would have to work hard for this," which prompts the reply, "You would, if I wasn't tied down." Note that this is said while she reaches down to grab his/your unwilling erection.
"Also, could you move my gurney to a room that doesn't have a ton of windows before we do this? No? Okay, whatever."
Then, after one party has presumably achieved orgasm, the first thing out of Michael's mouth is the decidedly unsexy "Okay, now can you let me go?"
To be fair, she does back off if you tell her to. But considering that she appears to be your only way out of an otherwise deadly situation, telling the aggressive and violent German lady with a giant gun "no" is a little bit different than telling your girlfriend you have a headache. Or, even better, imagine the exact same scene with the genders reversed, including the part where the armed male soldier reaches into the female captive's pants to see how aroused she is. It seems like that might possibly have generated some complaints.
Instead, letting SIE get what she wants is a requirement for two of the game's achievements. Remember, kids: "Yes, but only because you might leave me to die otherwise" means "No."
